TANK-VALVE.

SPECIFICATION forming part of Letters Patent No. 380,153, dated March 27, 1888.

I Application filed November 10, 1887. Serial No. 254,791. (No model.)

To all whom it may concern:

Be it known that I, HENRY O. W EEDEN, of

Boston, in the county of Suffolk and State of Massachusetts, a citizen of the United States, have invented certain new and useful Improvements in Tank-Valves, of which the following is a specification.

The object of my invention is to provide an improvement in slow-closing valves for governing the discharge of water from tanks, especially those used to supply water-closets and similarstructures.

In the accompanying drawings I have represented in vertical section a valve embodying my presentimprovements,showing it at Figure 1 in its position when closed, and at Fig. 2 in its position when open.

to flush a water-closet or other similar structure should be provided with devices whereby, after the valve has been raised and released, its descent may be retarded, so as to permit an increased discharge of water from the tank. In my present invention I accomplish this result by constructing the valve and its accompanying parts in the manner hereinafter described. A represents the valve-seat and dischargeorificc. Within this is a cross-bar, B, from which rises vertically a plunger, 0, at the upper portion of which are formed guide-pieces D with intermediate water-ways, as shown. E represents the valve proper, to which is secured a hollow chamber, F,adapted to encircle the plunger 0, and working thereon with a loose fit. To the upper portion of this chamber may be attached, as shown, the chain G, by which the valve is to be raised.

The operation of the device is as follows: The device being seated as shown in Fig. 1, when it is desired to discharge water from the tank the valve is raised to the position shown in Fig. 2. This permits water not only to flow out of the outlet at A, but also to rise and 5 fill the chamber F, the water entering for this purpose through the water-ways between the guides D D. If, now, the pull be released, the valve descending by gravity incloses a certain amount of water between the chamber F and the plunger 0, which water gradually es- 5) capes as the valve descends by its gravity between the plunger and the chamber. As the aperture between these two parts is very small, the descent of the valve is thus retarded, and by regulating the amount of weight in the valve the time of its descent will be regulated accordingly.

I am aware that it-is not broadly new with me to construct a retarded tank-valve in which the retardation is accomplished by means of a dash-pot, as, for example, in the valve represented in Letters Patent No. 89,151 of April 2Q, 1869, and I accordingly make no claim to such construction, broadly. Furthermore, I am aware that a slotted discharge-pipe the slots of which are opened and closed by raising or lowering the valve of a tank is shown in saidKeane patent, and I do not wish to be understood as making a claim to any such construction, broadly.

I claim The improved tank-valve herein described, having the seat and outlet portion A of ordinary construction, a cross-bar, 13, extending across said outlet, a slotted plunger, 0, supported upon the cross-barandprovided atitsupper portion with vertical guide-pieces D D and intermediate water-ways,and a circular valve, E, adapted to open and close the outlet. and provided with a vertical cylindrical retardingchamber, F, the said chamber being made" liquid-tight at the top and encircling and working loosely upon the plunger, all substantially as set forth. 7 i

In testimony whereof I have hereunto subscribed my name this 5th day of November, A. D. 1887.

HENRY o. WEEDEN.
